Wow is all i can say. Really wish i would have taken a before and after video. Before i could literally hear almost no bass due to the rattles come from the roof. After 10 sq ft of AT 60 mil deadener and a roll of weather stripping the roof literally has 0 rattles. I was absolutely amazed by this product. I used 25 sq ft of fat mat 50 or 60 mil, whatever it is, on my trunk lid and it did next to nothing. Gonna be buying 40 sq ft of AT to do my rear deck then doors and what i have left is going on the trunk/spare tire well as thats where the rattles have traveled. Thanks to AT for the free 10 sq ft, you now have a new customer.
